I have to say knowing someone who has a salvaged Tesla, that this doesn't sound right at all. He's a very happy owner of an early (2013?) Tesla. Biggest complaint after 4 years is the rear toe-in, but that was fixed at the alignment shop. Maybe there are issues with the newer ones, but he loves his and the few issues he's had were easily fixed. He uses (and pays for) Supercharging.

"If you own a salvaged Tesla, you can’t get a single part (not even a screw or a little plastic bolt cover), you can’t use the supercharger".

With ebay and other on-line tools there is a thriving 'Junkyard' scene for Teslas... parts are available and relatively cheap. Maintenance levels are lower (no ICE/transmission) and most parts have German equivalents. Yes, there are 'makers', 'hackers', and backyard mechanics... some of them are dangerous (crazy car mods). Biggest concerns are the cooling system for the batteries and the wiring harness since those are safety critical and unique to Tesla.

On the other hand we have have 60k deadly Takata airbags driving around on the road (post recall) and no-body (not NHTSA or the insurance companies) are trying to do something about it. Think about all of the bad fuel pumps and rotting hoses on old gas-powered cars...
